I'm trying to change rendering of a list column on list view page.

After a few tutorials and some hair pulling I managed to create an xslt for a calculated and currency field (from fldtypes_XXXXXX.xsl):

<xsl:template match ="FieldRef[@Name='MarkCalc']" mode="Text_body">
  <xsl:param name="thisNode" select="."/>
  <xsl:value-of select="$thisNode/@*[name()=current()/@Name]" disable-output-escaping ="yes"/>
</xsl:template>

<xsl:template match="FieldRef[@Name='CurrencyTest']" mode="Number_body">
  <xsl:param name="thisNode" select="."/>
  <b><xsl:value-of disable-output-escaping="yes" select="$thisNode/@*[name()=current()/@Name]" /></b>
</xsl:template>

Then I tried to do the same for a lookup field, but it just won't work. This is my last attempt (I copied it from SharePoint designer). What am I missing?

<xsl:template match="FieldRef[(@Encoded) and @Name='Lookup1']" mode="Lookup_body">
  <xsl:param name="thisNode" select="."/>
  <b><xsl:value-of select="$thisNode/@*[name()=current()/@Name]" disable-output-escaping="yes" /></b>
</xsl:template>
